In this case, first studied in Ref. [1]}, the model presents retrieval only when \(\alpha =0\) , i.e., the number of memorized patterns stays of \(O(1)\) . As the number of memories grows like \(N\) , retrieval is lost (in the thermodynamic limit). This lack of retrieval might be explained by the spherical symmetry in the free energy that the continuous memory variables introduce. As soon as the number of patterns is allowed to be extensive, the system does not know how to distinguish the Gaussian memories.
